Did s104 as one of the first OU modules, quite enjoyed it but it depends what you interested in, it covers nearly all areas of science. SK277 was my first level 2 module and loved it, my favorite upto now, gained a distinction and found the module info really good, nothing too scary on the exam. Just completed s294 and even though I have a keen interest in cell biology I struggled in the exam, with it being the first presentation it was all over the place, waiting for the result atm but not waiting for a good mark I dont think! lol has anyone done sk320? nearly over half way through this module and its really good, a level 3 module to consider if you like cell biology and pathology.
